Description

Technical Field

[0001] This invention relates to the field of integrated pipeline planning technology, and in particular to a method for controlling the vertical elevation of intersecting pipelines in integrated urban municipal pipeline planning. Background Technology

[0002] In order to make reasonable use of the underground space of urban roads and to rationally arrange the location of underground municipal pipelines (usually including rainwater, sewage, reclaimed water, water supply, gas, heating, information, power lines and municipal integrated pipe corridors, etc.), and to orderly, scientifically and rationally arrange the longitudinal laying space of various professional municipal pipelines (because the construction units and design units of various professional municipal pipelines are different and information is not shared), it is necessary to carry out comprehensive planning of urban municipal pipelines.

[0003] The comprehensive planning of urban municipal pipelines mainly involves studying spatial layout strategies for municipal pipeline projects from multiple perspectives, including horizontal positioning, vertical control, and overall planning coordination. Based on the coordination of various elements within the road space, the goal is to achieve the safety, efficiency, and feasibility of various municipal pipeline projects within limited space resources. The main tasks of this planning include: coordinating the layout of various municipal pipelines; determining the orientation and location of municipal pipeline laying; determining the horizontal spacing between adjacent municipal pipelines and the vertical control spacing between intersecting municipal pipelines; and determining the control elevation and cover depth for underground municipal pipelines.

[0004] Vertical elevation control of pipelines is the most important and challenging part of comprehensive urban municipal pipeline planning. It primarily involves determining the control elevations (not absolute elevations, but rather control lines that the bottom or top of municipal pipelines must not exceed) for gravity flow pipelines crossing each other, based on their characteristics and initial cover requirements. This allows for the rational arrangement of vertical intersections between various pipelines. Current technologies suffer from pipeline collisions and intersections, leading to wasted underground space and difficulties in later design modifications. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, the purpose of this invention is to provide a method for controlling the vertical elevation of intersecting pipelines in the comprehensive planning of urban municipal pipelines. This invention solves the problems of pipeline collisions, disordered design, and waste of underground space resources caused by untimely communication and poor coordination among multiple professional design schemes.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] A method for controlling the vertical elevation of intersecting pipelines in integrated urban municipal pipeline planning, comprising:

[0008] A method for controlling the vertical elevation of intersecting pipelines in integrated urban municipal pipeline planning, comprising:

[0009] Obtain the location of the intersection point of each gravity flow pipeline, and obtain the elevation of the gravity flow pipeline and the road design elevation based on the location of the intersection point of each gravity flow pipeline; the gravity flow pipeline is divided into: sewage pipeline and rainwater pipeline;

[0010] Using the branch lines of rainwater pipelines and sewage pipelines as control conditions, the elevation of the main line of the non-gravity flow pipeline is controlled and edited to obtain the controlled elevation of the main line of the non-gravity flow pipeline. The controlled elevation of the main line of the non-gravity flow pipeline is then used to control and edit the elevation of the branch lines of the non-gravity flow pipeline; or

[0011] Using the main lines of rainwater pipelines and sewage pipelines as control conditions, the elevation of the branch lines of non-gravity flow pipelines is controlled and edited to obtain the controlled branch elevations of the non-gravity flow pipelines. The elevation of the main line of the non-gravity flow pipelines is then controlled and edited using the controlled branch elevations of the non-gravity flow pipelines.

[0012] Preferably, the step of controlling and editing the main elevation of the non-gravity flow pipeline using the branch lines of the rainwater pipeline and the sewage pipeline as control conditions to obtain a controlled main elevation of the non-gravity flow pipeline, and using the controlled main elevation of the non-gravity flow pipeline to control and edit the branch elevation of the non-gravity flow pipeline includes:

[0013] Determine whether the non-gravity flow pipeline intersects with the gravity flow pipeline. If so, obtain the difference between the designed road elevation and the branch elevation of the stormwater pipeline, and the difference between the designed road elevation and the branch elevation of the sewage pipeline, to obtain a first difference. The first difference is the largest difference among the differences between the designed road elevation and the branch elevation of the stormwater pipeline, and the differences between the designed road elevation and the branch elevation of the sewage pipeline. Subtract the first backfill requirement, the outer diameter of the main line of the non-gravity flow pipeline, and the distance between the non-gravity flow pipeline and the gravity flow pipeline from the first difference to obtain a second difference. Determine whether the second difference is greater than 0. If so, determine that the branch elevation of the non-gravity flow pipeline is the difference between the designed road elevation and the first backfill requirement. The bottom elevation of the main line is the difference between the road design elevation and the outer diameter of the non-gravity flow pipeline main line, and the first soil cover requirement value. If not, the third difference is obtained by subtracting the top elevation of the sewage pipeline branch, the outer diameter of the non-gravity flow pipeline main line, and the distance between the non-gravity flow pipeline and the gravity flow pipeline from the bottom elevation of the rainwater pipeline branch. The third difference is then determined to be greater than 0. If so, the top elevation of the non-gravity flow pipeline main line is determined to be the difference between the bottom elevation of the rainwater pipeline branch and the distance between the non-gravity flow pipeline and the gravity flow pipeline. The bottom elevation of the non-gravity flow pipeline main line is determined to be the difference between the bottom elevation of the rainwater pipeline branch and the distance between the non-gravity flow pipeline and the gravity flow pipeline, and the outer diameter of the non-gravity flow pipeline main line.

[0014] Using the road design elevation as the control surface, the spacing between the main lines of each pipeline is determined sequentially downwards. If the spacing is greater than the sum of the outer diameter of the branch line of the non-gravity flow pipeline and the spacing between the non-gravity flow pipeline and the gravity flow pipeline, then the space is suitable for laying the branch line of the non-gravity flow pipeline. The top height of the branch line of the non-gravity flow pipeline is the bottom height of the main line of the previous non-gravity flow pipeline minus the outer diameter of the branch line of the non-gravity flow pipeline. The bottom height of the branch line of the non-gravity flow pipeline is the bottom height of the main line of the previous non-gravity flow pipeline minus the outer diameter of the branch line of the non-gravity flow pipeline and the spacing between the non-gravity flow pipeline and the gravity flow pipeline.

[0015] Preferably, the step of controlling and editing the branch elevation of the non-gravity flow pipeline using the main trunk lines of the rainwater pipeline and the sewage pipeline as control conditions to obtain the controlled branch elevation of the non-gravity flow pipeline, and using the controlled branch elevation of the non-gravity flow pipeline to control and edit the main trunk elevation of the non-gravity flow pipeline includes:

[0016] Determine whether the non-gravity flow pipeline intersects with the gravity flow pipeline. If so, obtain the difference between the designed road elevation and the top elevation of the main trunk of the stormwater pipeline to obtain a first difference. Subtract the first backfill requirement, the outer diameter of the branch of the non-gravity flow pipeline, and the distance between the non-gravity flow pipeline and the gravity flow pipeline from the first difference to obtain a second difference. Determine whether the second difference is greater than 0. If so, determine that the top elevation of the branch of the non-gravity flow pipeline is the road design elevation minus the first backfill requirement, and the bottom elevation of the branch of the non-gravity flow pipeline is the road design elevation minus the first backfill requirement and then the outer diameter of the branch of other pipelines. If not, subtract the top height of the sewage main line, the outer diameter of the branch line of the non-gravity flow pipeline, and the distance between the non-gravity flow pipeline and the gravity flow pipeline from the bottom height of the main line of the rainwater pipeline to obtain a third difference value. Then determine whether the third difference value is greater than 0. If it is, determine that the top height of the branch line of the non-gravity flow pipeline is the difference between the bottom height of the main line of the rainwater pipeline and the distance between the non-gravity flow pipeline and the gravity flow pipeline, and the bottom height of the branch line of the non-gravity flow pipeline is the difference between the bottom height of the main line of the rainwater pipeline and the distance between the non-gravity flow pipeline and the gravity flow pipeline, and the outer diameter of the branch line of the non-gravity flow pipeline.

[0017] Using the road design elevation as the control surface, the spacing of the branches of each pipeline is determined sequentially downwards. If it is greater than the sum of the outer diameter of the main branch of the non-gravity flow pipeline and the spacing between the non-gravity flow pipeline and the gravity flow pipeline, then the space is suitable for laying the main branch of the non-gravity flow pipeline. The top height of the main branch of the non-gravity flow pipeline is the bottom height of the branch of the previous non-gravity flow pipeline minus the outer diameter of the main branch of the non-gravity flow pipeline. The bottom height of the main branch of the non-gravity flow pipeline is the bottom height of the branch of the previous non-gravity flow pipeline minus the outer diameter of the main branch of the non-gravity flow pipeline and the spacing between the non-gravity flow pipeline and the gravity flow pipeline.

[0018] Preferably, obtaining the location of each intersection of gravity flow pipelines, and obtaining the elevation of the gravity flow pipelines and the road design elevation based on the location of each intersection of gravity flow pipelines includes:

[0019] Obtain the location of the intersection of each gravity flow pipeline, and obtain the corresponding road design station number based on the location of each intersection of gravity flow pipeline.

[0020] Based on the road design station number, obtain the design elevation of the road at the intersection, the top and bottom elevations of the stormwater main line, the top and bottom elevations of the stormwater branch line, the top and bottom elevations of the sewage main line, and the top and bottom elevations of the sewage branch line.

[0021] Preferably, the main trunk lines of the rainwater pipeline and the main trunk lines of the sewage pipeline are in the same direction.

[0022] Preferably, the branch lines of the rainwater pipeline and the branch lines of the sewage pipeline are intersecting.

[0023] Preferably, the non-gravity flow pipeline includes:

[0024] Information pipelines, power well pipelines, reclaimed water pipelines, gas pipelines, water supply pipelines, direct buried heating pipelines, heating tunnels, and power tunnel pipelines.

[0046] The purpose of this invention is to provide a method for controlling the vertical elevation of intersecting pipelines in the comprehensive planning of urban municipal pipelines. This invention solves the problems of pipeline collisions, disordered design, and waste of underground space resources caused by untimely communication and poor coordination among multiple professional design schemes.

[0047] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] like Figure 1 As shown, this invention provides a method for controlling the vertical elevation of intersecting pipelines in integrated urban municipal pipeline planning, comprising:

[0049] Step 100: Obtain the location of the intersection of each gravity flow pipeline, and obtain the elevation of the gravity flow pipeline and the road design elevation based on the location of the intersection of each gravity flow pipeline; the gravity flow pipeline is divided into: sewage pipeline and rainwater pipeline; such as the main line of rainwater pipeline - information pipeline branch line, and the branch line of sewage pipeline - rainwater pipeline main line.

[0050] Step 200: Using the branch lines of the rainwater pipeline and the sewage pipeline as control conditions, control and edit the main line elevation of the non-gravity flow pipeline to obtain the controlled main line elevation of the non-gravity flow pipeline. Then, use the controlled main line elevation of the non-gravity flow pipeline to control and edit the branch line elevation of the non-gravity flow pipeline. Alternatively, using the main lines of the rainwater pipeline and the sewage pipeline as control conditions, control and edit the branch line elevation of the non-gravity flow pipeline to obtain the controlled branch line elevation of the non-gravity flow pipeline. Then, use the controlled branch line elevation of the non-gravity flow pipeline to control and edit the main line elevation of the non-gravity flow pipeline.

[0051] like Figure 2 As shown, the specific steps of the intersection elevation scheme are as follows: Using the main lines of the rainwater pipeline and the sewage pipeline as control conditions, the elevation of the non-gravity flow pipeline branch lines is controlled and edited to obtain the controlled elevation of the non-gravity flow pipeline branch lines. Using the controlled elevation of the non-gravity flow pipeline branch lines to control and edit the elevation of the non-gravity flow pipeline main lines includes:

[0052] Determine whether the non-gravity flow pipeline intersects with the gravity flow pipeline. If so, obtain the difference between the designed road elevation and the branch elevation of the stormwater pipeline, and the difference between the designed road elevation and the branch elevation of the sewage pipeline, to obtain a first difference. The first difference is the largest difference among the differences between the designed road elevation and the branch elevation of the stormwater pipeline, and the differences between the designed road elevation and the branch elevation of the sewage pipeline. Subtract the first backfill requirement, the outer diameter of the main line of the non-gravity flow pipeline, and the distance between the non-gravity flow pipeline and the gravity flow pipeline from the first difference to obtain a second difference. Determine whether the second difference is greater than 0. If so, determine that the branch elevation of the non-gravity flow pipeline is the difference between the designed road elevation and the first backfill requirement. The bottom elevation of the main line is the difference between the road design elevation and the outer diameter of the non-gravity flow pipeline main line, and the first soil cover requirement value. If not, the third difference is obtained by subtracting the top elevation of the sewage pipeline branch, the outer diameter of the non-gravity flow pipeline main line, and the distance between the non-gravity flow pipeline and the gravity flow pipeline from the bottom elevation of the rainwater pipeline branch. The third difference is then determined to be greater than 0. If so, the top elevation of the non-gravity flow pipeline main line is determined to be the difference between the bottom elevation of the rainwater pipeline branch and the distance between the non-gravity flow pipeline and the gravity flow pipeline. The bottom elevation of the non-gravity flow pipeline main line is determined to be the difference between the bottom elevation of the rainwater pipeline branch and the distance between the non-gravity flow pipeline and the gravity flow pipeline, and the outer diameter of the non-gravity flow pipeline main line.

[0053] Using the road design elevation as the control surface, the spacing between the main lines of each pipeline is determined sequentially downwards. If the spacing is greater than the sum of the outer diameter of the branch line of the non-gravity flow pipeline and the spacing between the non-gravity flow pipeline and the gravity flow pipeline, then the space is suitable for laying the branch line of the non-gravity flow pipeline. The top height of the branch line of the non-gravity flow pipeline is the bottom height of the main line of the previous non-gravity flow pipeline minus the outer diameter of the branch line of the non-gravity flow pipeline. The bottom height of the branch line of the non-gravity flow pipeline is the bottom height of the main line of the previous non-gravity flow pipeline minus the outer diameter of the branch line of the non-gravity flow pipeline and the spacing between the non-gravity flow pipeline and the gravity flow pipeline.

[0054] The method of using the controlled elevation of the non-gravity flow pipeline branch to control and edit the elevation of the non-gravity flow pipeline trunk is simply referred to as "determining the trunk based on the branch".

[0055] Furthermore, the process of controlling and editing the elevation of the non-gravity flow pipeline trunk line using the branch lines of the rainwater pipeline and the sewage pipeline as control conditions to obtain a controlled elevation of the non-gravity flow pipeline trunk line, and using the controlled elevations of other trunk lines to control and edit the elevation of the non-gravity flow pipeline branch lines includes:

[0056] Determine whether the non-gravity flow pipeline intersects with the gravity flow pipeline. If so, obtain the difference between the designed road elevation and the top elevation of the main trunk of the stormwater pipeline to obtain a first difference. Subtract the first backfill requirement, the outer diameter of the branch of the non-gravity flow pipeline, and the distance between the non-gravity flow pipeline and the gravity flow pipeline from the first difference to obtain a second difference. Determine whether the second difference is greater than 0. If so, determine that the top elevation of the branch of the non-gravity flow pipeline is the road design elevation minus the first backfill requirement, and the bottom elevation of the branch of the non-gravity flow pipeline is the road design elevation minus the first backfill requirement and then the outer diameter of the branch of other pipelines. If not, subtract the top height of the sewage main line, the outer diameter of the branch line of the non-gravity flow pipeline, and the distance between the non-gravity flow pipeline and the gravity flow pipeline from the bottom height of the main line of the rainwater pipeline to obtain a third difference value. Then determine whether the third difference value is greater than 0. If it is, determine that the top height of the branch line of the non-gravity flow pipeline is the difference between the bottom height of the main line of the rainwater pipeline and the distance between the non-gravity flow pipeline and the gravity flow pipeline, and the bottom height of the branch line of the non-gravity flow pipeline is the difference between the bottom height of the main line of the rainwater pipeline and the distance between the non-gravity flow pipeline and the gravity flow pipeline, and the outer diameter of the branch line of the non-gravity flow pipeline.

[0057] Using the road design elevation as the control surface, the spacing of the branches of each pipeline is determined sequentially downwards. If it is greater than the sum of the outer diameter of the main branch of the non-gravity flow pipeline and the spacing between the non-gravity flow pipeline and the gravity flow pipeline, then the space is suitable for laying the main branch of the non-gravity flow pipeline. The top height of the main branch of the non-gravity flow pipeline is the bottom height of the branch of the previous non-gravity flow pipeline minus the outer diameter of the main branch of the non-gravity flow pipeline. The bottom height of the main branch of the non-gravity flow pipeline is the bottom height of the branch of the previous non-gravity flow pipeline minus the outer diameter of the main branch of the non-gravity flow pipeline and the spacing between the non-gravity flow pipeline and the gravity flow pipeline.

[0058] The method of editing the elevation of non-gravity flow pipeline branches by using the controlled elevation of other trunk lines is simply referred to as "determining the branch based on the trunk line".

[0059] After initially determining the vertical elevation control scheme for pipelines at intersections by using branch lines to determine trunk lines or trunk lines to determine branch lines, it is necessary to optimize and adjust the vertical arrangement sequence of different pipelines according to their construction characteristics and cross-sectional dimensions. From top to bottom, information pipelines should be arranged first, followed by power wells, reclaimed water pipelines, gas pipelines, water supply pipelines, and direct-buried heating pipelines, and finally heating tunnels and power tunnels.

[0060] Specifically, taking information pipelines as an example: First, determine whether they intersect with branches of rainwater pipelines and sewage pipelines. If they intersect, calculate C - the soil cover requirement for the information pipeline and the corresponding outer diameter of the information pipeline. Check whether the distance between the information pipeline and the rainwater and sewage pipelines is greater than 0. If it is greater than 0, it proves that the soil cover above the rainwater pipeline can be used to lay the information pipeline. The top height of the information pipeline is C - the soil cover requirement for the information pipeline, and the bottom height is E - the soil cover requirement for the information pipeline - the outer diameter of the information pipeline.

[0061] If it is less than zero, it means there is no soil cover above the rainwater. Then calculate whether the distance between the E-information pipeline and the intersection of the information pipeline with the rainwater pipeline and the sewage pipeline is greater than 0. If it is greater than zero, it means there is a laying condition for the branch of the rainwater pipeline and the branch of the sewage pipeline. The top height of the information pipeline is Y4 - the distance between the intersection of the information pipeline and the rainwater pipeline, and the bottom height is Y4 - the distance between the intersection of the information pipeline and the rainwater pipeline - the outer diameter of the information pipeline.

[0062] Based on the established elevations of all trunk lines and control branch line elevations, calculate whether the following values ​​are greater than 0: A - Top elevation of each type of trunk line - Information cover requirement - Information pipeline diameter - Intersection distance between the information pipeline and other pipelines. If greater than 0, it indicates that there are conditions above the trunk line for laying information pipelines. The top elevation of the information pipeline is A - Information pipeline cover requirement, and the bottom elevation is A - Information pipeline cover requirement - Information pipeline diameter. If less than 0, it indicates that there are no conditions above the pipeline for cover. The top elevation of the information pipeline is the bottom elevation of the trunk line - Intersection distance with the information pipeline, and the bottom elevation is the bottom elevation of the trunk line - Intersection distance with the information pipeline - Information pipeline diameter. Calculate the control top and bottom elevations of the information pipeline and all intersecting pipelines sequentially. Then, using the top elevation as the criterion, select the group with the smallest top elevation as the final control elevation of the information branch line.

[0063] Furthermore, obtaining the intersection points of each gravity flow pipeline and determining the elevation of the gravity flow pipelines based on these intersection points includes:

[0064] Obtain the intersection point of each gravity flow pipeline and obtain the corresponding road design station number based on the intersection point of each gravity flow pipeline.

[0065] Based on the road design station number, obtain the design elevation of the road at the intersection, the top and bottom elevations of the stormwater main line, the top and bottom elevations of the stormwater branch line, the top and bottom elevations of the sewage main line, and the top and bottom elevations of the sewage branch line;

[0066] Based on the design elevation of the road at the intersection, the top and bottom elevations of the stormwater trunk line, the stormwater branch line, the sewage trunk line, and the sewage branch line, the distance between the design elevation of the road and the top elevation of the stormwater branch line, the distance between the design elevation of the road and the top elevation of the stormwater trunk line, the elevations of the stormwater trunk line and the sewage trunk line, and the elevations of the stormwater branch line and the sewage branch line are calculated. Y2-W1=D;Y4-W3=E;A-Y1=B;A-Y3=C;Where A is the design elevation of the road at the intersection, B is the distance between the design elevation of the road at the intersection and the top elevation of the main line of the stormwater pipeline, C is the distance between the design elevation of the road at the intersection and the top elevation of the branch line of the stormwater pipeline, D is the distance between the bottom elevation of the main line of the stormwater pipeline and the top elevation of the main line of the sewage pipeline, E is the distance between the bottom elevation of the branch line of the stormwater pipeline and the top elevation of the branch line of the sewage pipeline, W1 is the top elevation of the main line of the sewage pipeline, W3 is the top elevation of the branch line of the sewage pipeline, Y1 is the top elevation of the main line of the stormwater pipeline, Y2 is the bottom elevation of the main line of the stormwater pipeline, Y3 is the top elevation of the branch line of the stormwater pipeline, and Y4 is the bottom elevation of the branch line of the stormwater pipeline.

[0067] Furthermore, the main trunk lines of the rainwater pipeline and the main trunk lines of the sewage pipeline are aligned in the same direction.

[0068] Furthermore, the branches of the rainwater pipeline and the sewage pipeline intersect.

[0069] Furthermore, the non-gravity flow pipeline includes:

[0070] Information pipelines, power well pipelines, reclaimed water pipelines, gas pipelines, water supply pipelines, heating pipelines, and power tunnel pipelines.

[0071] Furthermore, the editing sequence for controlling and editing the elevation of the non-gravity flow pipeline trunk and / or the non-gravity flow pipeline branch is as follows:

[0072] The pipelines are, in order: the information pipeline, the power well pipeline, the reclaimed water pipeline, the gas pipeline, the water supply pipeline, the heating pipeline, and the power tunnel pipeline.

[0073] This embodiment also discloses a pipeline elevation control strategy:

[0074] (1) When there is a vertical conflict between pipelines in an engineering project, the following provisions shall apply: pressure pipelines shall yield to gravity flow pipelines; flexible pipelines shall yield to inflexible pipelines; branch pipelines shall yield to main pipelines; small-diameter pipelines shall yield to large-diameter pipelines; temporary pipelines shall yield to permanent pipelines.

[0075] (2) Figure 3 As shown, when there is sufficient soil cover above the rainwater pipeline and sewage pipeline at the intersection of engineering pipelines, other non-gravity flow pipelines should be arranged above the rainwater and sewage pipelines first, and branch lines with smaller non-gravity flow diameters should be arranged above the main line.

[0076] Note: Based on factors such as road planning elevation, minimum soil cover requirements for pipelines, and pipe diameter, the top elevation of the branch line of the rainwater pipeline is used to control the bottom elevation of other trunk lines, and the bottom elevation of the branch line with the greatest burial depth is used to control the top elevation of other trunk lines.

[0077] (3) Figure 4-5 As shown, when the soil cover above the stormwater and sewage pipelines at the intersection of engineering pipelines is only sufficient to meet the laying requirements of one group of other types of pipelines, it is advisable to prioritize laying smaller-diameter non-gravity flow pipeline branches above the stormwater and sewage pipelines. Larger-diameter non-gravity flow trunk lines should preferably utilize the space between the branches of the stormwater and sewage pipelines to pass through.

[0078] (4) Figure 6 As shown, when the soil cover above rainwater and sewage pipelines at the intersection of engineering pipelines cannot meet the requirements for laying other types of pipelines, it is advisable to prioritize arranging the branch lines of non-gravity flow pipelines with smaller diameters above the main line.

[0079] (5) Figure 7-8 As shown, when the soil cover above the branch of the rainwater pipeline is insufficient and the diameter difference between the main and branch lines of the rainwater pipeline in the road section is large, the connection method of the branch lines of the rainwater pipeline and the branch lines of the sewage pipeline in the road section can be appropriately adjusted according to the gravity flow pipeline layout scheme to reduce the burial depth of the pressure flow pipeline.

[0080] Note: When there is a significant difference in pipe diameter between the main and branch lines of the stormwater and sewage pipelines within a road section, and there is ample room for vertical adjustment of the branch lines, the connection method (top-side connection, in-pipe connection, bottom-side connection) between the branch lines of the stormwater and sewage pipelines and the diameter of the pipelines running in the same direction can be reasonably determined by combining the elevation of the stormwater and sewage pipelines and the diameter of the pipelines running in the same direction. This allows the pipelines running in the same direction to pass above the branch lines of the stormwater pipelines first, thereby reducing project costs.

[0081] (6) Figure 9-11 As shown, when rainwater and sewage pipelines are laid on one side of the road and there is no soil cover above them for non-gravity flow pipelines, the vertical spatial relationship between pressurized pipelines and gravity flow pipelines can be adjusted by combining the pipeline layout plan and taking advantage of the bendable characteristics of pressurized pipelines such as water supply, gas, and reclaimed water, thereby reducing the overall soil cover of the pipelines.

[0082] Note: When rainwater and sewage pipelines are laid on one side of a road and there is no soil cover above them for non-gravity flow pipelines, the flexibility of pressurized pipelines such as water supply, gas, and reclaimed water pipelines can be utilized. When they intersect with rainwater and sewage pipelines, they can be laid below the rainwater and sewage pipelines, passing through them before being laid upwards, thereby reducing the overall soil cover of the pipelines.

[0083] (7) Figure 12-15As shown, when there is no soil cover above the gravity flow pipeline, the burial depth of the non-gravity flow pipeline can be reduced by adjusting the direction or layout of rainwater and sewage flow, increasing the spacing between branch pipelines, etc.

[0084] Note: When non-gravity flow pipelines intersect with stormwater and sewage pipelines, and are unable to cross due to existing facilities such as subways or civil defense structures below, adjustments to the flow direction or layout of the stormwater and sewage pipelines can be attempted to avoid intersections, thus enabling the smooth laying of the non-gravity flow pipelines. When all municipal pipelines have pre-reserved branches, trunk line crossings are difficult and the burial depth is deep. The distance between stormwater and sewage pipeline branches and other non-gravity flow branches should be increased to provide space for vertical elevation adjustments of the trunk lines.

[0085] Based on the characteristics of various pipelines, such as soil cover requirements, materials, and pipe diameters, this invention uses the road design elevation and the elevations of stormwater and sewage pipelines at the intersections of gravity flow pipelines as control interfaces. It adopts a "main trunk determines branch" or "branch determines main trunk" approach, aiming to minimize the total soil cover requirement at the intersections. This method involves a step-by-step, layer-by-layer, and scientifically rational arrangement of vertical spatial intersections of various municipal pipelines. This invention solves the problems of pipeline collisions, disordered design, and wasted underground space resources caused by untimely communication and poor coordination among multiple professional design schemes.

[0086] Furthermore, in this embodiment, all pipeline intersections should satisfy the following conditions:

[0087] The planning control elevation for intersections of municipal pipelines should be determined based on the elevation of gravity flow pipelines. Provided that the minimum soil cover requirements for all types of pipelines are met, all types of municipal pipelines should, as far as possible, pass above stormwater and sewage pipelines. If there are no suitable conditions for laying stormwater and sewage pipelines above them, other municipal pipelines can be arranged to pass through the gaps between stormwater and sewage pipelines. If there are no suitable conditions for passing between stormwater and sewage pipelines above or between them, then municipal pipelines should be arranged to pass through the space below the stormwater and sewage pipelines.

[0088] When municipal pipelines are laid at intersections, factors such as the pipeline's horizontal location, pipe diameter, pipe material, and soil cover requirements should be considered comprehensively. The optimal goal is to minimize the overall soil cover of the pipelines at the intersection, and the elevation of the pipelines at the intersection should be planned and controlled. It is recommended that pipelines with shallower soil cover requirements and smaller diameters be laid on the uppermost layer, while power tunnels, heating trenches, water supply trunk lines, and integrated utility tunnels be laid on the lower layers.

[0089] The beneficial effects of this invention are as follows:

[0090] This invention of a vertical control method can reasonably control the intersection of municipal pipelines, avoid pipeline collisions and intersections, and make intensive use of underground space. By providing control elevations similar to control lines, it avoids pipeline collisions, makes intensive use of underground space, and also leaves some room for adjustment in the later design and construction of pipelines. It has both rigid and flexible control, that is, to achieve the optimal soil cover depth for pipeline intersections while respecting the feasibility of pipeline construction.
